| titleOfInvention | Composite separation membrane based on in situ growth of organic framework structure based on fluorine-containing copolymer and its preparation method and application |
| abstract | The invention discloses a composite separation membrane based on an in-situ growth organic frame structure of a fluorine-containing copolymer and a preparation method and application thereof. A certain proportion of perfluoro-2,2-dimethyl-1,3-dioxole (PDD), tetrafluoroethylene (TFE) and terminal amino olefins are randomly copolymerized to obtain a product that can be further reacted and modified. It can be mixed with PDD‑co‑TFE binary copolymers in different proportions to form membranes, and covalent organic framework structure sheets are grown in situ on the surface of membrane substrates through Schiff base reaction. The group is introduced into the framework structure to form a coordination structure to obtain a fluorine-containing copolymer composite separation membrane. The composite separation membrane prepared by the method of the invention significantly enhances the bonding force between the fluorine-containing copolymer layer and the organic frame structure layer through amine group bridging, and realizes the adjustment of the internal pore size through the modification of the internal structure of the pores of the organic frame structure layer. , which can efficiently and selectively separate organic gases and inorganic gases (oxygen, carbon dioxide, etc.), and has extremely high practical value. |
